DRIVEWAY CONSTRUCTION.

Specification of Letters Patent.

Patented Jan. 4, 1921.

Application filed May 21, 1920. Serial No. 383,234.

T 0 aZZ whom it may concern Be it known that I, EMIL O. MEELBERG, acitizen of the United States residing at Minneapolis, in the county of llennepin and State of Minnesota, have invented certain new and usefulImprovements in Driveway Construction, of which the following is aspecification.

This invention relates to drive ways for automobiles and the object isto provide an elficient and durable metallic track especially adaptedfor use in private yards, between streets and garages. The invention isclearly illustrated in the accompanying drawing, in which:

Figure l is a top view of a portion of one of the tracks.

Fig. 2 is a bottom view of a portion of one of the tracks as seen inFig. 1.

Fig. 3 is a sectional view of the double track complete, and showing themethod by which automobile wheels are supported.

Referring to the drawing by reference characters, A designatesmyimproved sheet metal tracks, each of which is composed of a plurality ofinterlocked sections, as shown in Figs. 1 and 2, such sections beingriveted together by rivets B. Each track A is formed at its sides withupwardly curved integral reinforcing portions C which reduce theflexibility of the track. The edges of said portion are also curveddownwardly and inwardly so as to prevent any possibility of such edgesfrom cutting the tires D which travel on the track.

The underside of each track A is provided with crossed diagonal braces Ewhich are riveted at their ends in the tracks at F. Such braces thusprevent twisting or bending of the track and together with thereinforcing portions C combine to form a rigid and substantial trackconstruction. As the braces E become pressed and embedded in the groundG they act in a further capacitv to hold the tracks in. a permanent andfixed position on the ground.

Having now, therefore fully shown and described my invention, what Iclaim to be new and desire to protect by Letters Patent 1s:

1. A device of the class described consisting of a pair of parallelmetallic tracks, the lateral edge portions of each of said tracks beingcurved inwardly thereupon to form reinforcements.

I 2. A device of the class described consistmg of a pair of parallelsectionally formed metallic tracks, diagonal braces fixed at their endsto the underside of each of said tracks.

3. A device of the class described consisting of a pair of parallelsectionally formed metallic tracks, diagonal braces fixed at their endsto the underside of each of said tracks, and longitudinal reinforcingportions integral with the sides of said tracks.

In testimony whereof I afiix my signature.

EMIL O. MEELBERG.
